Stemborers and Striga weeds cause significant losses to maize production throughout Africa. Maize yield losses due to stemborers can vary from 20-40%. Striga weeds infest 40% of the arable land in sub-Saharan Africa, causing an annual crop loss of US$ 7 to 13 billion. Around the Lake Victoria basin, infestation by Striga weed causes 30 to 100% loss in maize yield. Weeding for Striga control is both time-consuming and labor-intensive. The use of insecticides for stemborer control is not only expensive and harmful to the environment but is also ineffective.
